| Abstract: | This paper introduced efficiency problem of HP and IP turbine for 300MW steam turbine with double flow LP. The improving strategy had been put forward for through flow design in HP and IP turbine. The advanced design scheme had been carried out and the economic level had been estimated by 3D-NS CFD method for the improved unit. Both the calculation results and the measured heat rate of fact improved machine indicated that heat rate level was the state of the art in similar units. |
